Be it known that we, RUDOLPH FLIGK and l/VALTER M. BROWNING, citizens ofthe United States, and residents, respectively, of Sheridan, in thecounty of Madison and State "of Montana, and Glasgow, in the county "ofValley and State of Montana, have invented certain new and usefulImprovements in Docking Machines, of which the followingisaspecification. I

This invention relates to docking machines for lambs.

.-An important object is to provide a docking machine for lambs having.two pairs of cutting blades, onepa'ir of which may be heated while theother pair is in use.

A further object of the invention is to provide simple means wherebyeither pair of blades may be'arranged in an operative position when theother pair becomes cool.

Another object of the invention is to provide a docking machine which iseconomical to operate, of highly simplified construction and cheap tomanufacture Other objects and advantages of the in vention will beapparent during the course of the following description.

In the accompanying drawing forming part of'this' application and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a side elevation of the improved docking machine applied toa suitable support. T

Figure 2 is a plan view of the machine applied. I

Figure 3 is a vertical sectional view through the machine, the Viewillustrating a pair of coacting blades.

Figure 4 is a transverse sectional viewtaken on line H of Figure 3.

- Figure 5 is a perspective of an insulating sheet embodied in theinvention.

Figure 6 is a perspective of a relatively movable disk embodied in theinvention.

In the drawing wherein for the purpose ofi'llustration is shown apreferred embodi ment of the invention, the numeral 5 desig nates anelongated casing which is coma posed of sections 6 and 7 having inwardlydirected flanges connected by means of fastening bolts 8. The fasteningbolts 8 of course extend through the sides of'the sec tions 6 and 7 andcause the edges of the disks having cutting inwardly projecting flangesto lie snugly in contact with each other. The casing 5 may be secured toasuitable support 10 by means of clamps 11 and is preferably secured inan inclined position in the manner illustrated in Figures 1 and 3.

With reference to Figure 3 it will be observed that the casing 5 isprovided with alongitudinally extending heating chamber which issupplied withheatifrom a gasoline torch 12 of any desired type. Themouth 13 of the torch 12 discharges into an inlet opening 15 at thelower portion of the casing. The heat from the torch 12 is directedthrough the casing and more particularly into the heating chamber and isdischarged through an outlet opening 16 inthe upper portion of thecasing, the said outlet opening being provided by cutting away portionsof the inwardly extending flanges of the casing. Suitable hangers 17 maybe provided for supporting the torch 12 in its proper position withrelation to the heating chamber. Vith reference to the foregoing it willbe seen that a high degree of heat is passed through the heating chamberof the casing in the use of the machine. 1

A suitable metallic plate 19 is arranged between the section 7 and thesupport 10 and has inwardly extending flanges '20 to form a, supportingmeans for a sheet of insulating material 21 such as asbestos. Theinsulating sheet 21 prevents the casing from burning-the support 10. 7

The docking means includes a pair of cutting disks one of which ismovable with.

relation to the other. However both of the disks may be rotated forarranging a new pair of blades in an operative positionand for againheating the pair of blades which may have become cool. i p t -herelatively movable blade is in the nature of a disk having oppositelyarranged segments provided with cutting edges 23. The movable disk 22has its oppositely arranged segments provided with thickened portions 24which provide relativelywide cutting edges and which also provide stopshoulders 25. The cutting blades 23 which are two in number cooperatewith similar blades of the relatively stationary disk.

With particular reference to Figure-6 it will be noted that the movableblade 22 has its hub secured to an annular flange 28. by means of rivets29, the said. annular flange being formed at one end of a sleeve bearing30. The sleeve bearing receives the attaching portion 31 of a pair ofoppositely arranged arms 32 by means of whichthe bearingSO may bemanually rotated for operating the movable disk 22. A'handle 34 has itsforward portion provided with a socket 35 which receives one of the arms32 and which is adapted to be rocked for rotating the disk a limitedextent.

The sleeve bearing 30 is rotatably extend.

7 contact with the segments of the disk 22.

One'edge portion of each segment of the stationary disk 40 is thickenedas indicated at 4]. to provide a pair of stop shoulders 42 which engagethe adjacent edges'of the movable'segments and thereby limit the rota--tion of one disk with relation to the other.

7 side of the shaft.

The thickened portions 41 of which there are two provide cutting edgesor blades 43 with which the movable cutting edges 23 coact', When themovable blade 22 is operated the blades 23 and 43 are brought intocontact for performing the desired operation and they do not pass eachother. The relatively stationary blade which is designated by thenumeral 40 has its hub secured to a flange. 44 by means of rivets, thesaid flange being formed at one end of a shaft 45. The shaft 45 isextended through the sleeve bearing 30 and has one end slotted asindicated at 46. A locking handle 47 is pivotally connectedto theslotted portion of the head 45 and may be swung to either Vith referenceto jFig-,

ures 1 and 4it will be noted that the locking handleis adapted to bereceived within a slot 50 in a laterally projecting bracket 51 carriedby the section 6. hen the lock ing handle 47 is thus secured to thebracket 51 the shaft 45 is prevented from rotating.

With the shaft 45 thus held against rotation'the disk 40 is held in arelatively stationary position. However, the disk 22 is permitted tomove sothat the blades 23 and 43 may be brought into contact.

In operation the torch is mounted so that the heatfrom the same will bedirected into the heating chamber in the casing 5. The heat thusdirected through the heating chamber will be caused to heat the lowerportions of the relatively stationary and movable disks since the diskshave their lower portions received within said champosite side of theshaft 45 whereupon the shaft 45 is rotated and the locking handle 47again engaged with the bracket 51. When the shaft 45 is thus rotatedboth of the disks are rotated for exposing a new;

pair of cutting blades and for subjecting the cooled blades to theaction of the heat.

A docking machine constructed in ac cordance with this inventionoperates with no. loss of blood to the animal since the wound is searedand quickly heals Also the machine may be rapidly operated since it ismerely necessary toswing the handle 34 in the direction indicated by thearrow in Figure 1 for contacting the blades 23 and 43. Actual testsperformed on a large herd of lambs demonstrated that the machine can berapidly'operated and will cause no loss of blood or weight by theanimals.
